The wrench should be used as a tool when load and unload ballasts.
When loading and unloading ballasts, it is necessary to pay attention to safety, ballasts easy
to hit your feet. It is suggested that two people cooperate or find professional maintenance
personnel when you need loading or unloading ballasts.
4.4 The use of electrical systems
The electrical system of each serie of tractor is dc power supply, the calibration voltage is
12V, the negative ground is grounded, the single line and double color system.
All kinds of electrical equipment adopt different wire diameters and different colored wires,
which are connected according to certain rules and requirements, thus forming a complete
machine circuit. See appendix 3 for the electrical schematic diagram.
4.4.1 Generator and voltage regulator
The generator is the main power supply of the tractor, which is used to supply power to the
electrical equipment and charge to the battery, and the voltage regulator is used to limit the
generator to make the output voltage in the regulation value.
Attention should be paid to:
(1) It is not allowed to check whether the generator is generated by using B+ and ground fire;
otherwise, the silicon rectifying element will be burned.
(2) When the engine is in operation, it is not allowed to remove the connection wires on the
generator.
(3) The generator is negative grounded, and shall not be wrong, otherwise, the silicon
rectifier element or regulator will be
burnt.
(4) If the engine is running at a
moderate speed, but the charging
indicator will not be extinguished,
indicating that the generator or
regulator is out of order and the tractor
should be stopped and checked
immediately.
